DUIVIPING APPARATUS.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed May 11,1906. Serial No. 316,389.

To all whom it may concern.-

Be it known that I, SAMUEL W. HorKINs, a citizen of the United States, residing at Enterprise, in the county of Dickinson and State of Kansas, have invented certain new and useful Improvements in Dumping App aratus, of which the following is a specification.

The invention relates to improvements in dumping apparatus of that description which is employed in elevating ordinary road-vehicles, such as a wagon, and turning the same so that the load can be emptied into a depository at a lower level, such as a car, bin, or other receptacle.

The invention consists in the novel construction, combination, and arrangement of parts, such as will be hereinafter fully described, pointed out in the appended claims, and illustrated in the accompanying drawlngs.

In the accompanying drawings, inwhich similar reference characters designate corresponding parts, Figure 1 is a side elevation, broken away in parts, of dumping apparatus embodying the invention. Fig. 2 is an end elevation. Fig. 3 is a plan view.

The circular base 1 is supported in a horizontal position by the sleepers 2, embedged O- tatable on the base is the circular platform 3, carried by the wheels 4, journaled in the brackets 5, secured to the under side of the platform and traveling on the base. The platform is held in place by the pivot 6 on the base and engaging at its upper end with the bearing 7 in the under side of the platform. On the platform are the uprights 8, carrying at their upper ends the parallel guideways 9,.

connected by the cross-pieces 10. Each guideway consists of the tread 11 and the side flange 12. The guideways are inclined at an angle of about forty-five degrees, although the inclination may vary to suit different conditions and requirements. To the lower end of the central upright 8 is secured the inner end'of the horizontal lever 13, the outer end of which projects beyond the platform. By means of the lever the platform can be rotated. Between the upper ends of the guideways is the catch 14, adjustably mounted in the cross-piece 10. In the bracket 15 on the cross-piece, outside of the catch, is journaled the sheave 16, over which a rope may be passed.

Adjacent to the base 1 is the fixed approach leading from the ground to the guideon the sleepers 18, embedded in the earth,

and to their upper ends are secured the inclined guideways 19, connected by the crosspieces 20. The lower ends of the guideways are seated on the sill 21. These guideways have the same formation and are spaced the same as those on the rotatable platform. The inclination of the guideways is the same as that of the guideways 9.

The lower ends of the guideways 9 and the upper ends of the guideways 19 areshaped so as to register with each other when the rotatable platform is moved for the purpose of bringing them into alinement. Pivoted to the lower ends of the guideways 9 are the hooks 22, adapted to engage the eyebolts 23 on the upper endsof the guideways 19. By means of the hooks and eyebolts the fixed and movable guideways can be locked together to form a continuous track.

The operation of the apparatus is as follows: By means of the lever 13 the rotatable platform 3 is turned until the fixed and movable guideways register with each other. Further movement of the platform is prevented and the guideways are locked in alinement by moving the hooks 22 into engagement with the eyebolts 23. Care is taken to see that the catch 14 is in a lowered position. The apparatus is now ready for the elevation of a vehicle. The vehicle that is to be unloaded is moved into position at the foot of the fixed approach with its wheels in line with the guideways and the front ones ready to move onto the same. It is to be observed that the treads of the guideways are quite wide, so that vehicles of different widths can be accommodated, and the side flanges have considerable height to control the direction of the wheels, so that they cannot leave the guideways. A rope is passed over the pulley 16, and its end is fastened to the front axle or other suitable part of the vehicle. Strain is exerted on the rope by any suitable power, and the vehicle is drawn up the incline until it rests entirely upon the movable guideways, as shown by dotted lines in Fig. 1. The vehicle is held in place by moving the catch 14 upward back of the front axle. After the catch has been adjusted the strain on the rope can be relieved. After the hooks 22 have been disengaged from the eyebolts 23 the rotatable platform can be turned by means of the lever 13 until the rear end of the vehicle is above the depository that is to receive the load. The end gate of the vehicle is raised and the contents are permitted to escape into the receptacle. After the load has been deposited the rotatable platform is turned back to its original position and locked. When the catch 14 is lowered, the vehicle can travel backward down the incline to the ground, being held in check by the rope.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In dumping apparatus, a rotatable platform, inclined guideways mounted on said platform in an elevated position, a fixed approach, inclined guideways on said approach leading to the lower ends of the guideways on the platform, and means for locking both guideways together.

2. In dumping apparatus, a rotatable platform, inclined guideways mounted onsaid platform in an elevated position, an adjust able catch operating to hold a vehicle on said guideways, a pulley mounted in the line of travel on said guideways, a fixed approach, and inclined guideways. on said approach leading to the lower ends of said guideways on the platform.

3. In dumping apparatus, a base, a platform rotatable on said base and provided with a bearing in its under side, a pivot on said base and journaled in said bearing, wheels interposed between said base and said platform to carry the latter, inclined guideways mounted on said platform in an elevated position, a catch operating to hold a vehicle on said guideways, a fixed approach, inclined guideways on said approach leading to the lower ends of said guideways on the platform, means for locking both guideways together, and a pulley mounted in the line of travel of the guideways on the platform.
